Description

Aquatic product coating preservation solution carrying burdock polyphenol and preparation and use methods thereof
Technical Field
The invention relates to an aquatic product coating preservation solution carrying burdock polyphenol and a preparation method and a use method thereof, belonging to the technical field of food preservation processing.
Background
The processed aquatic products have high water activity, rich nutrient components and strong in-vivo enzyme activity, and are easy to generate the phenomena of protein degradation, fat oxidation and bacterial breeding during storage, transportation and sale, so that the putrefaction and the deterioration are caused, and the commercial value of the processed aquatic products is seriously influenced. How to adopt natural, green and safe technical means to effectively delay the decrease of the edible quality and the safe quality of processed aquatic products is a research hotspot in the field of food preservation at present.
The coating preservation takes macromolecules (such as polysaccharide, protein, lipid and the like) as materials, and plasticizers, cross-linking agents and the like are added to cover the surfaces of aquatic products in a wrapping or coating mode so as to achieve the effects of water resistance, air permeability, bacteria resistance and the like. In order to further improve the preservation effect of the composite coating, researchers usually strengthen the functions of the composite coating by natural active molecules such as essential oil, vitamin C and the like, so as to inhibit the oxidation and bacterial reproduction of aquatic products. In the practical application process, the active ingredients in the coating film are chemically degraded and easily diffused to the surrounding environment, thereby causing the loss of the efficacy of the coating film.
Patent CN201911140310.2 discloses a preservative film for biological preservation of aquatic products, which adopts D-tryptophan/polylactic acid and sodium chloride to compound, thereby destroying bacterial biofilm and inhibiting bacterial growth. However, the coating film prepared by this technique has a low content of antioxidant active substances, thereby impairing the freshness-retaining effect. Patent CN201711326317.4 discloses an aquatic product preservative mainly comprising sodium hexametaphosphate, sodium tripolyphosphate, sodium pyrophosphate, ascorbic acid, glycerol and other components. The technology relates to the use of phosphate, which is easy to migrate into the muscle tissue of aquatic products, and the ingestion of a large amount of phosphate can increase health risks. Patent CN201810431028.9 discloses a composite fresh-keeping coating liquid for aquatic products, a preparation method and a use method thereof, which comprises 0.5-2% of chitosan, 0.5-2% of lauroyl arginine ethyl ester hydrochloride, 0.5-2% of essential oil, 0.5-1% of grease and the balance of distilled water. In the method, the essential oil is not encapsulated by microencapsulation, but the oil is mixed and dispersed in the preservative film. Therefore, essential oils are easily volatilized and diffused, not taking advantage of the maintenance of their efficacy; patent CN201910162654.7 discloses a preparation method of a tea polyphenol liposome/lysozyme-chitosan slow-release coating film applied to fish slice preservation, and the related polyphenol liposome is of a double-layer film structure and has strong fluidity.

6. The method for preparing the burdock polyphenol-loaded aquatic product coating preservation solution as claimed in claim 3, wherein in the step 2.6, in the process of carrying out high-intensity ultrasonic treatment on the primary emulsion for 10-15min, an ultrasonic treatment instrument is set to be switched on/off for 2s at 200-400W.
7. A coating preservation solution for aquatic products carrying burdock polyphenol, which is characterized by being prepared by the method of any one of the claims 1 to 6.
8. A use method of an aquatic product coating preservative solution carrying burdock polyphenol is characterized in that the aquatic product coating preservative solution prepared by any one of the methods of claims 1-6 is used for preserving processed aquatic products, and specifically comprises the following operation processes:
soaking the processed aquatic product in a film-coating preservation solution for 5-10min, draining in a sterile environment, soaking the processed aquatic product in a 3-5% calcium chloride cross-linking agent solution for 1-2min, rinsing in clear water, draining in the sterile environment, packaging, and refrigerating or freezing at low temperature.
